webber fatburner

Almost every HPSB will have a single to double, some have vee out the tail.. unless it is a small wave grovler which usually have a straight single concave to push through more mush. Webber's do have a serious deep double concave running through them though. i actually prefer a less deep concave, for east coast waves too deep of a concave in my opinion slow the board to much creating to much drag. but not always the case.. hope this helps...

 

There's a lot of variables that go into what kind of bottom a board will have. Some of the things to consider closely are rocker, rail edges, and wave type. Put a straight edge across the bottom of the board and slide it fore and aft to see exactly what's going on... where the concaves start, their deepest point, are the doubles in the single ("single to double concave") or does the single fade and doubles take over ("triple concave"), whether there's any vee along the length of the concave... Really pay attention to the details.

Here are some basic "rules of thumb" for me... I prefer single concaves for smaller waves, and combinations of concaves for bigger/better waves. I also like deeper concaves for boards for bigger surf with more rocker, and more subtle concaves for smaller or weaker surf and flatter rockers. The exception to these rules is super wide boards, in which deep double concaves work well due to the fact that you're essentially riding one half of the board at a time. The Sweet Potato is a good example, and that's what I think the Fatburner is trying to achieve as well, in addition to opening up the performance envelope a bit to handle better surf, particularly for a bigger rider.
